I have tried to download the Pax Logging binary file but I have
got error with the web site.

If I am not wrong, the idea would be included paxlogging bundle
as a required bundle, in order to get the libraries log4j and common-logging,
to launch this bundle and use in my bundle log4j as the same way as I did
without Equinox I mean in normal java applications, am I missing anything?

By the way, why I can’t to load the library org.apache.log4j.jar
in my bundle and simply to use it? If I have to use other external libraries,
what would I have to do in order to be able to use in Equinox framework?

Both of those implement the log4j logging API and use standard log4j
configuration property/xml formats for configuration, which is convenient if
that is what you know.

Both of those also implement Commons Logging and other logging APIs making it
very convenient in an OSGi container!

Furthermore, I included org.apache.log4j.jar in my classpath, either I
installed this library like a bundle. I also tried to install the bundle from
Orbit which implemented log4J, but I always have the same result.

Does anyone know what I have to do to use org.apache.log4J in Equinox?

I have either include import org.apache.log4j in Manifest.MF, I guess that
there is a way to load external libraries in Equinox framework, other times I
tried directly installing the jar file and it was fine, but with org.apache.lo4j
jar there is no way to get a good result.
